It is good practice to use a prefix, such as RP, in the name to help distinguish report parameters from other parameter types, such as data set parameters. For example, a report parameter used to filter on a quantityinstock field might be named RP_quantityinstock. The value you specify in Name appears as </a>the prompt to the report user if you do not specify a value for the next property, Prompt text. Rather than specify only a Name value for the parameter, you should use a technically descriptive value in Name, and provide a user-friendly value in Prompt text. </div>
